前言
笔者使用的mongo驱动是mgo, 这个使用的人比较多，文档也比较齐全
官网地址：http://labix.org/mgo
文档地址：https://godoc.org/labix.org/v2/mgo
源码地址：https://github.com/go-mgo/mgo
1. mgo包安装
|
1
|
go get gopkg.in/mgo.v2 |
但是貌似现在从gopkg.in下载不了，迂回一下，先从github上下载
|
1
|
go get github.com/go-mgo/mgo |
下载好了之后，在$GOPATH/src/下面创建文件夹gopkg.in/mgo.v2, 然后将github.com/go-mgo/mgo的内容，拷贝到gopkg.in/mgo.v2
2. 测试代码

这样要注意的一点是 GameReport 里面的字段都要首字母大写，否则不会写入mongo
